Autosoma Recessive

In genetic inheritance, all the genes passed from parents to child are either dominant (normal, or more likely to show up) or recessive (mutated, or less likely to show up). A trait that is autosomal recessive (referring to any possible trait other than male/female differentiation) that is passed from BOTH parents to the offspring can lead to appearance of a less-common characteristic such as auburn hair or disease such as cystic fibrosis.
